Owing to their large mass, they can give rise to significant perturbations in the spacetime metric around their locations. Such perturbations eventually would give rise to localized (hot)spots on the CMB. After describing the origin and properties of such hotspots, I will describe a few search strategies. In particular, I will demonstrate that neural networks can be versatile and powerful in looking for such hotspots and therefore constitute one of the unique probes of particle physics at very high energies. | 27 , Equity & Inclusion Committee (12:30 PM - 2:00 PM) Ekapob Kulchoakrungsun, Investigating Gravitational Effects on Large and Small-Scale Structures of the Universe (1:00 PM - 3:00 PM) + Abstract: Fred MacKintosh, Mechanical Phase Transitions and Elastic Anomalies in Fibrous Networks (4:00 PM - 5:15 PM) + Abstract: | 28 Babis Anastasiou, Building locally finite two-loop QCD amplitudes (2:00 PM - 3:15 PM) + Abstract: Zare (3:30 PM - 5:30 PM) Simeon Hellerman, Conformal field theory at large fermion charge (4:00 PM - 5:30 PM) + Abstract: |
